Answer 1

91:-

Answer:- (E) all of the choices are correct

-Most cases of  cystitis are caused by a type of Escherichia coli (E. coli) bacteria

-Ongoing use of a catheter, a tube used to facilitate the release of urine from the bladder, can increase your risk of bacterial infection, and damage tissues in the urinary tract. Both bacteria and damaged tissues can cause inflammation.

-Older men have a higher risk of having a UTI, especially if they are after the age of 50 . Most cases in older men are caused by the bacterium known as Escherichia coli, which is naturally present in the body.

Answer:- (C) toxic shock syndrome

Toxic shock syndrome (TSS) is a toxin-mediated acute life-threatening illness, usually precipitated by infection with either Staphylococcus aureus or group A Streptococcus (GAS), also called Streptococcus pyogenes. It is characterized by high fever, rash, hypotension, multiorgan failure (involving at least 3 or more organ systems), and desquamation, typically of the palms and soles, 1-2 weeks after the onset of acute illness. The clinical syndrome can also include severe myalgia, vomiting, diarrhea, headache, and nonfocal neurologic abnormalities.

BV is often caused by gardnerella vaginalis, the most common type of bacteria.

Puerperal Fever is known to be caused by an infection of haemolytic streptococci . Haemolytic Streptococci are bacteria that produce active haemolysins causing a clear zone of hemolysis on a blood agar medium in the area of the colony . The main bacterial strain seen is known as Streptococcus pyogenes.

Gas gangrene is most commonly caused by the Clostridium perfringens bacterium. In some cases, it may be caused by group A Streptococcus bacteria.

94:-

Answer:- (B) Second Trimester

A pregnancy is divided into trimesters: the first trimester is from week 1 to the end of week 12. the second trimester is from week 13 to the end of week 26. the third trimester is from week 27 to the end of the pregnancy.

After the 5th month of pregnancy treponema pallidum bacteria, the syphilis pathogen, can pass through the placental barrier. The infection of the fetus can lead to a miscarriage or leave behind congenital abnormalities.

95:-

Answer:- (A) chancroid

Chancroid is a bacterial sexually transmitted disease (STD) caused by infection with Haemophilus ducreyi. It is characterized by painful necrotizing genital ulcers that may be accompanied by inguinal lymphadenopathy

Chancroid may be successfully treated with certain antibiotics. Lesions and ulcers can be expected to heal within two weeks.

99:-

Answer:- (D) CD4

HIV uses a complex series of steps to deliver its genome into the host cell cytoplasm while simultaneously evading the host immune response. To infect cells, the HIV protein envelope (Env) binds to the primary cellular receptor CD4 and then to a cellular coreceptor. This sequential binding triggers fusion of the viral and host cell membranes, initiating infection.

100:-

Answer:-(D) Protozoan

Trichomoniasis (or “trich”) is a very common sexually transmitted disease (STD). It is caused by infection with a protozoan parasite called Trichomonas vaginalis.
